Abstract

A method for detecting a magnetic characteristic variable, in particular the magnetic field strength (H1), in a section (L1) of a core (2) through which a magnetic flux flows, wherein part (18) of the magnetic flux is branched off from the core (2) and is guided, at least in sections, in a magnetic shunt part (7), wherein the magnetic material of the shunt part (7) is not saturated, and wherein the magnetic characteristic variable (H1) is determined from this part (18) of the magnetic flux that has been branched off or from a variable derived therefrom using a sensor and evaluation device (8, 10).
